Survey of knowledge acquisition for blood transfusion of medical staff in Wuwei: an underdeveloped city in western China / 中国输血杂志

【Objective】 To investigate the knowledge acquisition status for blood transfusion of transfusion related medical staff in underdeveloped cities in western China and explore its influencing factors. 【Methods】 A questionnaire consisted of blood transfusion laws and regulations, clinical blood transfusion theory and blood transfusion technology was designed, randomly distributed to medical staff and blood transfusion departmenttechnicians of 17 secondary/tertiary hospitals in Wuwei and then collected on the spot. The knowledge acquisition of blood transfusion of each group was compared using statistical description method, and its influencing factors were analyzed by multivariate logistic regression analysis. 【Results】 A total of 507 questionnaires were issued, and 498 valid questionnaires (98.22%) were collected. The scores of transfusion related laws and regulations, blood transfusion theory and blood transfusion technology of doctor group(n=158), nurse group(n=239) and transfusion technician group(n=101)were 4.56-5.97(5.06±0.73)(P<0.01) vs 4.23-5.87(4.98±1.24)(P<0.01) vs 3.71-0.78 (4.15±1.34), 3.67-5.02(4.27±1.02) vs 3.76-5.12(4.06±0.75) vs 4.71-5.98(5.16±0.64)(P<0.01) and 3.41-5.76(3.82±0.56) vs 3.78-5.24(4.01±0.56) vs 3.77-5.46(3.82±0.59). Among the seven departments, blood transfusion department(n=51) won the highest score of above three types of knowledge [4.91-5.97(5.28±0.43) vs 5.03-5.92(5.36±0.59) vs 4.39-5.77(4.97±0.79)(P<0.01) ]. Univariate logistic regression analysis showed that age, occupation, professional titles, training times and hospital grade had an impact on the degree (score) of blood transfusion knowledge acquisition (P<0.05), and multivariate unconditional logistic regression analysis indicated that training times was an important influencing factor(P<0.01). 【Conclusion】 This survey revealed that the level of knowledge acquisition for blood transfusion among medical staff in Wuwei is generally low, and there is a significant difference between staff from hospitals of different grade and different departments. It is urgent to strengthen the training of blood transfusion for medical staff in western China.

Assessment on the Effects of Hepatitis B Prevention and Control Measures in Western China: A Comparison of Three Population-based Serosurveys / 生物医学与环境科学（英文）

Objective@#Despite the remarkable progress in efforts to control disease spread, the nationwide elimination of hepatitis B in China is still hindered by the persistently high rate of hepatitis B virus (HBV) infection in Western China. This study aimed to evaluate the strategy of hepatitis B prevention and control in Western China and identify potential areas and strategies for improvement.@*Methods@#Susceptible population vaccination, health education, professional training of doctors, and other prevention and control measures have been implemented in Wuwei city since 2010. Data were obtained from three representative cross-sectional serosurveys conducted in 2010, 2013, and 2015. The serum samples were subjected to enzyme-linked immunosorbent assays to detect the following seromarkers: HBV surface antigen (HBsAg), antibody against hepatitis B surface antigen (anti-HBs), and antibody against hepatitis B core antigen (anti-HBc). Estimates of variance were determined using Taylor series linearization methods.@*Results@#The three serosurveys revealed decreases in the prevalence of HBsAg (7.19% in 2010 @*Conclusion@#Although vaccine-based prevention and control measures reduced the rate of HBV infection in Wuwei City over time, the hepatitis B infection rate in children younger than 10 years was still higher than the national average level. Therefore, the prevention and control of mother-to-child transmission and the management of the infected should be the focus of future prevention and control work.

Investigation of the affordability of chronic diseases drug use in families from three provinces in Western China / 中国卫生政策研究

Objective:To investigate the affordability of chronic diseases and drug use in families three prov-inces in western China. Methods: Questionnaire survey was conducted in 6 cities in 3 west provinces of China—Guangxi,Shanxi and Sichuan. In each province,one provincial capital city and one medium-sized city were select-ed. 2 community health service centers,2 secondary hospitals and 2 tertiary hospitals were selected from each city as the survey sites. Questionnaire was designed and pre-tested in advance,and delivered to sample patients'families in survey sites by face-to-face interview. Results:Totally 900 questionnaires were sent out,and 838 were effectively re-ceived with effective recovery of 93.11%. 97.85% of patients participated in various medical insurance. The aver-age health expenditure of households was 1 364.84 yuan per month and accounted for 37.43% of the total expendi-ture;chronic diseases expenditure was 700.34 yuan per month and accounted for 51.31% of the total health expend-iture. The average monthly drug expenditure was 628.74 yuan and represented 16.73% of the total household ex-penditure. Surveyed family members mainly suffered from chronic diseases,hypertension and diabetes,and the heav-iest disease burden in families came from ischemic heart disease and chronic kidney disease. Different provinces, provincial capitals and non-provincial cities,and different levels of medical institutions have a greater difference in drug burden. Patients have experienced the effect of medical reform,but not familiar with the specific health care reform poli-cies. Conclusions and Suggestions:The surveyed patients'families were basically involved in the Medicare,but the burden of family medication for patients with chronic diseases was still heavy. Therefore,government should take further measures to improve the proportion of chronic diseases outpatient and reduce the burden of medication costs.

Sequence Analysis of cytb Gene in Echinococcus granulosus from Western China

Echinococcus granulosus is the causative agent of cystic echinococcosis with medical and veterinary importance in China. Our main objective was to discuss the genotypes and genetic diversity of E. granulosus present in domestic animals and humans in western China. A total of 45 hydatid cyst samples were collected from sheep, humans, and a yak and subjected to an analysis of the sequences of mitochondrial cytochrome b (cytb) gene. The amplified PCR product for all samples was a 1,068 bp band. The phylogenetic analysis showed that all 45 samples were identified as E. granulosus (genotype G1). Ten haplotypes were detected among the samples, with the main haplotype being H1. The haplotype diversity was 0.626, while the nucleotide diversity was 0.001. These results suggested that genetic diversity was low among our samples collected from the west of China based on cytb gene analysis. These findings may provide more information on molecular characteristics of E. granulosus from this Chinese region.
